Papyrus is one of the main characters in Undertale, the indie role playing game released by Toby Fox in 2015. The younger brother of Sans, he is an earnest skeleton who dreams of joining the Royal Guard and speaks in a loud, theatrical voice. His laugh, transcribed as Nyeh Heh Heh, became one of the game's most quoted lines and spread through fan comics, animations and soundboards. The short clip remains popular because it captures his personality in under three seconds and works as a reaction far outside the game.
